Description

The invention relates to a surgical device multiple socket for a high-frequency generator for connecting an electrosurgical instrument, an electrosurgical high-frequency generator, an electrosurgical device connector and an electrosurgical system. Moreover, the invention relates to a cable for an electrosurgical instrument and an electrosurgical instrument.

Electrosurgical instruments are used in surgery in particular for monopolar or bipolar cutting and / or coagulation of biological tissue. The energy for the electrosurgical instrument is provided by a radio frequency (RF) generator. To such a high frequency generator different electrosurgical instruments can be connected, each providing the same or different functionalities to the user. The connected electrosurgical instruments are powered by the radio frequency generator RF energy.

In order for the electrosurgical instruments to be connected to the radio frequency generator, currently used radio frequency generators generally provide different sockets for the various plugs of the electrosurgical instruments. Therefore, it is common in practice that the high-frequency generators have different sockets and thus no adapters for the individual electrosurgical instruments must be present. Surgical device connector systems are for example from the DE 10 2007 061 483 A1 known. In the known device connector systems openings, in particular for contact pins, are provided on the socket, wherein the functionality of the socket, for example by Codieröffnungen, is extended. As a result, in addition to the power transmission, for example, data can be transmitted.

The existing sockets, devices, and methods of connecting electrosurgical instruments to radio frequency generators offer several advantages, but further improvements are desirable.

It is therefore an object of the present invention to provide a surgical device multiple socket for a high frequency generator for connecting an electrosurgical instrument, an electrosurgical high frequency generator, an electrosurgical unit connector and an electrosurgical system, which are improved over existing sockets, devices and methods. It is a particular object of the present invention to provide a surgical device multiple socket for a high frequency generator for connecting an electrosurgical instrument, an electrosurgery radio frequency generator, an electrosurgical device connector and an electrosurgical system, which increase the compatibility of the devices used and / or an improved safety situation during and after a surgery process.

This object is achieved according to a first aspect of the invention by a surgical device multiple bushing for a high-frequency generator for connecting an electrosurgical instrument, in particular a bipolar applicator comprising a coaxial socket, which is adapted to receive a Koaxialsteckerelement, and a first contact opening, which is formed to receive a contact pin, and / or a second contact opening which is adapted to receive a contact pin.

Among other things, the surgical device multiple socket according to the invention is based on the recognition that a multiplicity of different electrosurgical instruments and, in addition, different plugs for these electrosurgical instruments are available in practice. This results in the high frequency generators being provided with a plurality of different sockets so that the electrosurgical instruments having different plugs can be connected to the high frequency generator. As a result, a reduction in the size of the high-frequency generators is limited possible because a not insignificant surface of the high-frequency generator for the provision of the jacks must be kept. In particular, the user-accessible front and side surfaces of the high-frequency generator can only be reduced in size or used for other purposes, such as displays or the like, since the provision of the different sockets occupies much space.

A reduction of this area is possible only with a restriction of the compatibility of the high-frequency generator, namely by the number of available sockets is reduced. However, this has the consequence that a smaller number of electrosurgical instruments can be connected to the high-frequency generator. In particular, the user is limited in his freedom to choose the instrument manufacturer, as manufacturers usually focus on a particular connector for their electrosurgical instruments. Another way to increase compatibility is to provide adapters, the use of which in surgery is associated with a number of disadvantages, such as the loss and use of a non-suitable adapter for a specific electrosurgical instrument or the restriction of data transmission through the adapter.

By combining a coaxial socket element with at least one contact opening, the surgical device multiple socket allows the connection of both coaxial plugs and plugs with two pins whose distance corresponds to the distance of the inner opening of the Koaxialbuchsenelements of the contact opening. Thus, the surgical device multiple socket already allows the combination of two hitherto separate jacks and thus the inclusion of second different connectors in one and the same socket. The inclusion of different plugs in the surgical device multiple socket is preferably not at the same time, but in each case when one of the respective connector is needed, the unneeded connector is preferably previously removed from the surgical equipment multiple socket.

In the present application, the respective plug to be inserted into the surgical device multiple socket is preferably a component of an electrosurgical instrument in order to connect the latter to a high-frequency generator. The surgical device multiple socket has, inter alia, the coaxial socket, which is in particular adapted to receive a Koaxialsteckerelement. A coaxial jack is used in particular for receiving a coaxial cable and for forming a detachable connection between one end of the cable, on which a Koaxialsteckerelement is arranged, and the coaxial socket.

The coaxial socket comprises an inner and an outer sleeve, which are arranged coaxially and preferably pushed into one another. The outer diameter of the inner sleeve preferably has a smaller dimension than the inner diameter of the outer sleeve. The inner diameter of the outer sleeve is preferably larger than the outer diameter of the inner sleeve. The outer diameter of the outer sleeve is preferably twice the size of the outer diameter of the inner sleeve. Furthermore, the end faces of the two sleeves at the proximal end of the coaxial jack are preferably substantially in a common plane.

Between the inner and the outer sleeve, an outer annular Koaxialbuchsenöffnung is formed. Inside the inner sleeve, an inner coaxial socket opening is formed.

The coaxial socket is in particular designed to receive a coaxial plug element, wherein the coaxial plug element has an inner contact pin and an outer contact ring. The outer contact ring has an inner recess in which the inner contact pin is arranged. Accordingly, the outer contact ring has the geometry of a sleeve completely or in sections along its axial extent. Thus, with the right choice of individual dimensions, a coaxial plug connection between the coaxial jack and the coaxial jack member is possible by inserting the inner contact pin into the inner coaxial jack opening and the outer contact ring into the outer annular coaxial jack opening. The coaxial connector thus obtained has the advantages of a very low electromagnetic interference and radiation and a good electrical shielding. Furthermore, it is possible to use the coaxial socket as a contact opening by a contact pin is guided in the inner coaxial socket opening of the coaxial socket.

The surgical device multiple bushing further comprises the first contact opening and / or the second contact opening, each adapted to receive a contact pin. The first and / or second contact opening has a preferably circular cross-section. Alternatively, preferably, the first and / or second contact opening on an oval or polygonal cross-section, wherein the corresponding contact pins then preferably also have such a geometry.

The first and / or second contact opening has a connection end, on which a contact pin can be inserted. At this connection end, the first and / or second contact opening has a defined diameter.

The coaxial socket and the first and / or second contact opening are arranged according to the invention on a single surgical device multiple socket. This arrangement allows the connection of different plugs to the multiple socket. The connectors may differ, for example, in the number and / or type and / or the spacing of the contact elements, such as contact pins and / or contact rings. For example, the connectors may differ with respect to the contact elements for the coaxial connector element. Furthermore, there is the possibility that the plugs differ with regard to the contact pins which are designed to be inserted into the first and / or second contact opening, for example with regard to the diameter and / or with respect to the geometry.

The coaxial socket has two functions in the inventive surgical device multiple socket. On the one hand, it is the function of the coaxial jack to accommodate a coaxial connector element. On the other hand, it is an object of the coaxial socket to receive a conventional contact pin in the inner coaxial socket opening formed by the inner sleeve. Thus, there is the possibility that a plug with two contact pins may be inserted into the surgical device multiple socket such that one contact pin engages the inner coaxial socket opening and the other contact pin engages in one of the contact openings. Through this dual use of the coaxial socket, the total number of required contact openings can be reduced at the surgical equipment multiple socket and the area utilization and compatibility can be optimized.

It has also been found to be advantageous that in the inventive arrangement of the contact opening (s) and the coaxial socket, the risk can be reduced by not properly connected electrosurgical instruments. This is due in particular to the fact that only a single electrosurgical instrument can be connected to the surgical device multiple socket according to the invention. Unintentional simultaneous connection of potentially incompatible devices, which could endanger personnel and / or the patient, can thus be ruled out. Even with a change of instruments is thus ensured that a new instrument can only be put into operation when the other instrument was safely separated from the high-frequency generator, which also increases the safety of staff and patients. Additional verification steps, whether no other, possibly incompatible devices are connected, can be omitted with high-frequency generators with the surgical device multiple socket, so that the treatment times can be shortened.

As a further advantage, it has also been found that the arrangement according to the invention of the coaxial socket and the first and / or second contact opening in or on the surgical device multiple socket has made it possible to connect a multiplicity of different electrosurgical instruments. The user is thereby enabled to select between a variety of electrosurgical instruments on the market.

In a preferred embodiment of the surgical device multiple bushing, this comprises a positioning opening, which is designed to receive a positioning pin. Preferably, the positioning opening usually offers no electrical function or no primary electrical function, but serves above all the safe and correct positioning of the plug in the desired position in the surgical device multiple socket. In particular, in plugs that would allow more than one way of positioning in the socket without a locator pin, a locating pin and corresponding locating aperture are advantageous for achieving univocal positioning of the connector in the surgical device hub.

Along an axial extent, the cross section of the positioning opening is preferably substantially circular. There is also the possibility that the positioning opening has an oval or polygonal cross section, wherein in particular a rectangular and / or square cross section is preferred.

The dimensions of this cross section, orthogonal to a longitudinal center axis, for example the diameter in a circular opening or the edge dimensions in an angular geometry, are preferably constant along the axial extent of the positioning opening. However, these dimensions may also vary along the axial extent of the positioning aperture, for example, to reduce toward the interior of the surgical device multiple socket. By such a configuration, there is a possibility that the positioning function of the positioning hole is further improved.

The provision of a positioning opening and a corresponding positioning pin on a plug can reduce the wear on the electrical contacts, in this case the coaxial socket and the first and / or second contact opening.

A preferred embodiment of the surgical device multiple socket provides that the coaxial socket, the first contact opening and the second contact opening are arranged such that a straight line connects centers of the coaxial socket, the first contact opening and the second contact opening.

This embodiment therefore provides that the coaxial socket and the contact opening or the contact openings are arranged in alignment. The fact that the line connects the centers of the coaxial socket and the first and second contact opening, it is clear that these openings are arranged in alignment. Such an arrangement allows in particular a more compact design of the surgical equipment multiple socket and thus in turn a more compact design of the entire high-frequency generator.

In a further preferred embodiment of the surgical device multiple bush it is provided that a center of the positioning opening connects at a distance to form a straight line the centers of the coaxial socket, the first contact opening and the second contact opening is arranged. Preferably, the straight line connecting the centers of the coaxial socket, the first contact opening and / or the second contact opening does not pass through the center of the positioning hole. The positioning opening is therefore preferably not in alignment with the electrically acting connections of the surgical device multiple socket. This non-aligned positioning opening has the particular advantage that thereby a secure and unambiguous positioning of a plug is improved.

A particularly preferred embodiment of the surgical equipment multiple socket provides that the positioning opening between the first or second contact opening and the coaxial socket is arranged eccentrically. This embodiment therefore provides that the positioning opening is not located on the straight line connecting the centers of the contact opening or contact openings and the coaxial socket. Furthermore, this embodiment provides that the positioning opening is not located in the middle between the coaxial jack and the contact opening adjacent thereto, so that the distance to the coaxial jack has a greater or smaller dimension than the distance to the nearest contact opening. Orthogonal to the straight line, connecting the centers of the coaxial socket, the first contact opening and / or the second contact opening, there is the possibility of a very small size of the surgical device multiple socket, whereby the total area requirement is reduced and the design of the high frequency generator can be positively influenced. In addition, this embodiment offers the advantage of a compact connector.

According to a further preferred embodiment of the surgical equipment multiple bush it is provided that the first and the second contact opening are arranged adjacent to one another. Accordingly, the first and the second contact openings are arranged such that no further openings or other relevant components of the surgical device multiple socket are arranged between the first and the second contact opening. In particular, this embodiment includes that on a connecting line which connect the center axes of the first and second contact opening, neither the coaxial socket nor, if appropriate, the positioning opening is arranged. Nevertheless, the adjacent arrangement of the contact opening preferably results in both openings still remaining integrally, so that the convolutions of the contact openings do not overlap.

According to another particularly preferred embodiment of the surgical device multiple bushing, it is provided that a distance between a center axis of the first contact opening and a center axis of the second contact opening is many times smaller than a distance between the center axis of the first contact opening and a center axis of the coaxial socket, and / or a distance between the center axis of the second contact opening and the central axis of the coaxial bushing, and / or a distance between a center axis of the positioning hole and the central axis of the coaxial bushing, wherein preferably the distance between the central axis of the first contact hole and the central axis of the coaxial bushing is greater than the distance between the center axis of the second contact hole and the center axis of the coaxial bushing, and further preferably the distance between the center axis of the second contact hole and the center axis of the coaxial bushing is greater than the distance between the center axis of the positioning hole and the center axis of the coaxial socket.

This arrangement results in that there is a region in which the coaxial socket is arranged, and a second region in which the contact openings are arranged. While both regions have a comparatively small extent, there is a large spacing between these two regions relative to the extent of these regions. In addition, this arrangement preferably results in that the positioning opening is located in the region or in the vicinity of the region of the first and / or second contact opening and is more distant from the coaxial socket. It is preferred that the distance of the first contact opening to the coaxial socket has the largest spacing between two openings on the surgical device multiple socket. Moreover, in this embodiment it is preferred that the positioning opening is arranged between one of the contact openings and the coaxial socket. Furthermore, it may be preferred that the positioning opening is arranged between the region in which the coaxial socket is arranged and the region in which the contact openings are arranged.

Such an arrangement of the coaxial socket and the contact openings is particularly advantageous in that this opens up the possibility that different connectors available on the market will be connected to the surgical device multiple socket. In particular, it is possible to use a plug with two contact pins with a first spacing and further to use a further plug with two contact pins, which have a second distance from each other, wherein the second distance, for example, has a smaller dimension than the first distance. moreover it is possible to use plugs of the aforementioned construction, which additionally has a positioning pin which can be inserted into the positioning opening of the surgical equipment multiple socket and thus ensures the correct positioning of the plug in the surgical equipment multiple socket.

In a further embodiment of the surgical device multiple bush it is provided that the distance between the central axis of the first contact opening and the center axis of the second contact opening is at most 10 times the diameter of the first and / or second contact opening. Particularly preferred is a maximum distance of 7.5 times the diameter, moreover, a distance which is at most 5 times the diameter is also preferred. In a further particularly preferred embodiment, the distance between the two contact openings is at most twice the diameter of the first and / or second contact opening.

In a further preferred embodiment, the distance between the contact openings is between 6 and 7 mm, preferably 6.58 mm.

In a particularly preferred embodiment of the surgical device multiple bush it is provided that the central axis of the coaxial bushing and the center axis of the first contact opening have a distance of 28-29 mm, in particular 28.58 mm to each other. Such a spacing allows the use of a plug with two contact pins whose center axes have a spacing of 28 mm to 29 mm, preferably 28.58 mm. Such connectors are often used in electrosurgery, so that this embodiment in particular increases the compatibility of a high frequency generator comprising such a surgical device multiple socket. In particular, by the inner coaxial socket opening and the spacing of these for the first contact opening, the application of a previously described connector is possible.

A further preferred embodiment of the surgical device multiple bushing provides that the central axis of the coaxial bushing and the center axis of the second contact opening have a distance of 21-23 mm, in particular 22 mm, to each other. Such a spacing of the coaxial bushing and the second contact opening allows the use of a plug having two contact pins with a spacing of 21-23 mm, in particular of 22 mm, to each other. Such connectors with contact pins having the aforementioned spacing are also often used in electrosurgery.

This arrangement of the coaxial socket and the second contact opening and the previously described arrangement of the coaxial socket and the first contact opening shows the flexibility of the surgical device multiple socket present here. The compact arrangement of the coaxial socket as well as the first and second contact opening makes it possible to connect a plug with a contact pin spacing of 21-23 mm and a plug with a contact pin spacing of 28-29 mm as well as a coaxial plug element in this compact surgical device multiple socket. In addition, it is clear that in the arrangement described above, no multiple occupancy of more than one plug and thus no connection of more than one electrosurgical instrument to the surgical device multiple socket is possible. This results in a significantly better security situation, since no wrong connection or unwanted multiple connection is made possible.

According to a further embodiment of the surgical device multiple bush it is provided that the coaxial bushing has a connection end into which a coaxial plug element can be inserted, and / or the first contact opening has a connection end into which a contact pin can be inserted, and / or the second contact opening is a connection end in which a contact pin is insertable, and / or the positioning opening has a connection end into which a positioning pin is insertable, wherein at least two terminal ends lie in a common plane.

The connection ends of the contact openings and / or the coaxial bushing and / or the positioning opening are to be understood in particular as meaning that an element to be inserted can enter or be introduced thereon. In particular, lying in a common plane means that the orthogonal clamp a two-dimensional geometry or a plane at the connection end of parallel center axes of the contact openings and / or positioning opening and / or coaxial socket. In a preferred variant of this embodiment, it is provided that at least three connection ends lie in a common plane and, alternatively, it is preferably provided that all connection ends lie in a common plane. An arrangement of three or more terminal ends in a common plane is advantageous in that a particularly compact design of the surgical equipment multiple socket can be achieved.

According to a further aspect of the invention, the object mentioned at the outset is achieved by an electrosurgical high-frequency generator comprising a surgical device multiple bushing according to one of the previously described embodiments. Such an electrosurgical high-frequency generator is initially characterized by being compatible with a variety of different electrosurgical instruments.

This results in a large selection of different connectors that can be used with the electrosurgical high frequency generator. These plugs may differ on the one hand with respect to the spacing of the intended contact pins, and on the other hand with the fact that the plug has a positioning pin or not. In addition, connectors may or may not have a coaxial connector element. The wide range of different plugs for electrosurgical instruments results in the requirement for high frequency generators that they are able to accommodate or be compatible with different plugs.

According to a further aspect of the present invention, the object mentioned at the outset is achieved by an electrosurgical device connector for insertion into a surgical device multiple socket according to one of the previously described embodiments, comprising a coaxial plug element, and at least one contact pin. Particularly preferred is such an electrosurgical device connector whose central axis of the Koaxialsteckerelements and the central axis of the contact pin 22-23 mm are spaced from each other. Alternatively, it is preferable that the center axis of the coaxial plug member and the center axis of the contact pin are spaced apart by 28-29 mm.

Moreover, it is preferable that the electrosurgical unit connector has a positioning pin which is formed and arranged to be inserted into a positioning hole. Such a connector can reduce or even eliminate various disadvantages of existing connector types, such connector not being used in previous solutions because the connector sockets in electrosurgical high frequency generators were generally incapable of receiving a connector having a coaxial connector element and a connector Contact pin has.

According to a further aspect of the present invention, the object mentioned at the outset is achieved by an electrosurgical system comprising a high-frequency generator according to the embodiment described above, and an electrosurgical instrument connected or connectable via the surgical device multiple socket of the high-frequency generator. Such a system allows not only a compact design, a flexible application of different electrosurgical instruments from different manufacturers as well as electrosurgical instruments with different plugs. Moreover, in the present system, it is not possible to make a faulty plug connection. Furthermore, it is not possible for the user to simultaneously connect more than one electrosurgical instrument to the high frequency generator. As a result, damage to the high frequency generator and / or the electrosurgical system can be avoided if necessary. The electrosurgical instrument connected or connectable to the surgical device multiple socket of the high frequency generator preferably has a previously described electrosurgical unit connector.

According to a further aspect of the present invention, the object mentioned is achieved by a cable for an electrosurgical instrument, characterized in that the cable is connected to an electrosurgical unit connector according to one of the previously explained aspects of the invention. The cable is preferably designed as a multi-core composite of a plurality of mutually insulated individual lines, wherein the individual lines are used in particular for the transmission of energy, preferably a stream, and / or for the transmission of information or data. In addition, the cable may also include another conduit for transporting fluids, such as coolants. The cable is also preferably sheathed with an insulating material, but the cable still typically preferably has elastic properties so that the cable is flexible. The connection of the cable to the electrosurgical device connector can, in particular for a user, be releasably designed, for example by a plug connection, or insoluble.

According to a further aspect of the present invention, the object mentioned is achieved by an electrosurgical instrument, characterized in that the electrosurgical instrument is connected to a cable according to the aspect described above. A connection at a connection point between the cable and the electrosurgical instrument can be made detachable or non-detachable, in particular for a user. A detachable connection between cable and electrosurgical instrument has the advantage that in case of failure of the cable or instrument only the defective component needs to be replaced and the intact component can continue to be used.

A permanent connection is understood to mean a connection which is not intended to be released by a user. An inseparable connection, in particular for the user, in turn has the advantage that an unintentional disconnection of the connection, in particular during the application of the electrosurgical Instruments, is prevented or at least aggravated, so that the safety during use, especially during a surgical operation, increased.

For further advantages, embodiments and detailed embodiments of these further aspects and their possible further developments, reference is also made to the description made above of the corresponding features and further developments of the surgical device multiple bushing.

Preferred embodiments of the invention will be explained by way of example with reference to the accompanying figures. Show it:

1 shows an embodiment of a surgical device multiple socket 1 , The surgery device multiple socket 1 extends from a first end 2 towards a second end 3 , The surgery device multiple socket 1 has a flat-oval outer contour, which has two parallel, opposite flanks and at the first and second ends 2 . 3 has a curved, in particular semicircular geometry. In a section adjacent to the first end 2 the surgical device multiple socket 1 is a coaxial jack 10 arranged.

The coaxial socket 10 is formed by two coaxially arranged sleeves. The inner sleeve 11 is from the outer sleeve 13 substantially enclosed in the radial direction. Furthermore, the inner sleeve 11 an outer diameter having a smaller dimension than the inner diameter of the outer sleeve 13 , As a result, two openings are formed through the gap between the outer and the inner sleeve 13 . 11 and the geometry-related cavity of the inner sleeve 11 be formed. The space between the outer and the inner sleeve 13 . 11 forms the outer annular coaxial socket opening 14 and inside the inner sleeve 11 formed space forms the inner coaxial socket opening 12 ,

The first contact opening 20 and the second contact opening 30 lie on a mental connecting line, starting from the first end 2 to the second end 3 runs. Here is the first contact opening 20 the second end 3 facing and the second contact opening 30 is the first end 2 or the coaxial socket 10 facing. The mental connection line, which is the first end 2 and the second end 3 joins, shares the surgery device multiple socket 1 mentally in two, horizontally separated halves, each having the same dimension in the vertical direction. On this line are the centers of the first contact opening 20 , the second contact opening 30 and the coaxial jack 10 ,

The surgery device multiple socket 1 also has a positioning hole 40 on. The positioning hole 40 has a circular cross section orthogonal to the central axis. The diameter is smaller than the diameter of the contact openings 20 . 30 , Further, the positioning hole is located 40 not on the connecting line, which are the centers of the contact openings 30 . 40 and the inner coaxial jack 10 connects, leaving the positioning hole 40 also not in alignment with the first and second contact opening 20 . 30 and the coaxial jack 10 lies.

In addition, the surgical device has multiple socket 1 the positioning hole 40 on.

3 shows an electrosurgical system 80 with a high frequency generator 50 and one Surgical device multiple socket according to the invention 300 to which a first electrosurgical instrument 61 connected. The electrosurgical system 80 includes the high frequency generator 50 with another embodiment of the surgical device multiple socket 300 and a first electrosurgical instrument 61 , The electrosurgical instrument 61 is with a connection cable 65 and via a connector (not shown) arranged thereon to the surgical device multiple socket 300 connected. The surgery device multiple socket 300 is at the high frequency generator 50 arranged. In addition, there is a second electrosurgical instrument 62 and a third electrosurgical instrument 63 ready. The electrosurgical instruments 62 . 63 each have a plug 60a . 60b on, with the plugs 60a . 60b are preferably different, for example, the distance between the pins is different.

It is also a fourth electrosurgical instrument 64 shown, which via another connection cable 65a with an electrosurgical device connector 70 connected is. The electrosurgical device connector 70 is in 4 shown in more detail. The connection of the fourth electrosurgical instrument 64 with the connection cable 65a can be designed as a fixed connection or as a connector, not shown, so that the cable 65a and the electrosurgical instrument 64 are preferably provided as separate assemblies.

4 shows an electrosurgical device connector 70 , The electrosurgical device connector 70 includes a contact pin 210 and a coaxial connector element 110 , The coaxial connector element 110 has a circular sleeve, this sleeve is designed thin-walled. Within this sleeve coaxially a contact pin is arranged, which in turn has a circular cross-section.

5 shows a plug with two pins 210 , The 5 schematically shows a commercial plug 60a for an electrosurgical instrument 62 or for connecting an electrosurgical instrument 62 with a high frequency generator 50 via a surgical device multiple socket. The plug 60a has two contact pins arranged on a base element 210 on. The contact pins 210 each have a longitudinal extent, wherein a circular cross-section is formed orthogonal to the longitudinal extent.

An electrosurgical instrument with a plug 60a according to 5 is suitable for the high frequency generator 50 out 2 to be connected. There is the possibility of two different connectors with pins 210 use. On the one hand, it is possible to use a plug whose one pin 210 into the inner coaxial socket opening 12 and its other contact pin 210 in the first contact opening 20 is introduced. In addition, it is possible to use a plug whose first contact pin 210 also in the inner coaxial socket opening 12 is introduced, but with the second contact pin 210 in the second contact opening 30 the surgical device multiple socket 1 . 300 is introduced.

The aforementioned insertion of the contact pins 210 in the openings is preferably done simultaneously, since the contact pins 210 fixed and lying in a plane on a main body of the plug 60a are arranged. Due to the fact that the surgical device multiple socket 1 . 300 includes the first and second contact opening, the possibility is given to insert plugs whose distance between the contact pins 210 is different. In addition, it is possible to use a plug which is suitable for a coaxial jack, such as a Koaxialsteckerelement 110 ,

In addition, it is possible, in addition to these available on the market plugs, a special electrosurgical device connector 70 to use, which is a coaxial connector element 110 and at least one contact pin 210 includes. It is also possible to use a plug which is a Koaxialsteckerelement 110 and two pins 210 in which case the spacing of the two contact pins 210 has the same dimension as the spacing of the two contact openings 20 . 30 , In addition, there is the possibility that a plug is used which comprises one of the aforementioned embodiments, but additionally comprises a positioning pin, wherein this positioning pin in the positioning hole 40 the surgical device multiple socket 1 . 300 is introduced.

In that different connectors, in particular different in terms of the number of pins 210 , the coaxial connector element 110 and the positioning pin (not shown) into the surgical device multiple socket 1 . 300 can be introduced, there is no longer the risk for the user that he introduces a plug in the wrong socket on the high-frequency generator and / or unintentionally incompatible devices simultaneously connects to the high-frequency generator or operates. Such interchanging or insertion of a plug into a wrong socket can lead to damage to the device or to the patient, in particular during the surgical procedure, so that the safety according to the invention is optimized during the surgical procedure.

In addition, the high number of compatible plugs results in only one Surgery equipment multiple socket into the high frequency generator 50 must be integrated and not as previously for each plug a specific designed for this connector socket. This in turn results in a smaller area requirement for the surgical device multiple socket, so that a more compact design of the high-frequency generator can be realized. Furthermore, electrosurgical instruments from different manufacturers and with different plugs can be applied to a single radio frequency generator, so that in a cost effective manner only a single radio frequency generator must be used, which can serve a variety of different electrosurgical instruments without the need for adapters ,
